A: We show specific maximum moment loads allowable for our linear actuators in our literature. Each actuator has a specific maximum pitch moment, yaw moment, and roll moment loads. If these values are exceeded, then we cannot guarantee the longevity of the components inside our actuators, and expected life of the actuator will be reduced.

Page E-30 shows that the EZS4D025-C model can handle a 8 Nm of dynamic (moving) pitch moment load, and a 51.2 Nm of static (resting) pitch moment load. This means that it can move a 10 N off-centered load where the center of gravity of the load is 5.12 meters away from the center of the carriage of the actuator (vertical direction).

For example, if you used an EZS4D for X-axis, and an EZS3D for Y-axis, and the X actuator is carrying the Y actuator, then the maximum load on the Y actuator is 2.3 kg or less, and the stroke is limited to 300 mm on the Y-axis.
